SC2020B/圓柱形電感式接近開關SC-2020B
以下是對上海雙旭電子有限公司 SC2020B/圓柱形電感式接近開關 的產品介紹，結合公開技術信息整理：
一、核心功能與原理
SC2020B 是一款圓柱形電感式接近開關，采用電磁感應原理實現非接觸式檢測。當金屬物體進入其感應區域時，開關內部的振蕩電路產生磁場變化，觸發無觸點信號輸出，無需機械接觸即可精準控制設備啟停或位置反饋46。
二、核心特性
-
穩定可靠
- 全封閉金屬外殼設計，具備防水、防震、耐腐蝕性能，適用于粉塵、油污等工業環境16。
- 無機械觸點磨損，使用壽命顯著延長，減少維護成本46。
-
響應精準
- 高頻響應特性，適應高速運動物體的檢測需求（如傳送帶、旋轉軸）46。
- 檢測距離可調，支持靈活安裝4。
-
強抗干擾性
- 內置抗電磁干擾電路，在電機、變頻器等強電磁場環境中穩定工作16。
